OP may or may not be a troll. But the idea is sound, there's no reason to log in and find 15k gold sitting in my harvesters backpack while she's out on a random island just chilling. For people to go to the village to collect gold. Adds annoyance, but also adds to the difficulty in the first place. VIllages are rather easy, and at least if people are forced to go take their gold from the stones, there chances for them to be attacked doing it. Also, it would stop encouraging zergs going all over Agon and capping villages miles away from their bases.

If they want to stop the gold flow to enemies they must first need to put the extra work into getting it all as well.
